Good corrugated design here but unfinished.
Excellent technical detail on Atlas shelters above and below ground. The general layout and architecture of everything is superb within the cost limits they operate inside of. I prefer steel bracing in the underflooring and stainless steel struts in the uprights because it lasts forever unlike wood. I also want to avoid treated wood and laminates because the offgassed products over the years can create a very toxic environment. It is worth noting that if your shelter already uses these materials you can neutralize most of these poisons through ozonation of the shelter when not occupied.
My next one is going to incorporate everything I have learned and then some from the previous two corrugated shelters I have constructed. I've made mistakes but the next one is going to get it right.
My next shelter is going to be 3.6 meters in diameter for headspace and is going to consist of an "H" shape (design to be posted here in the near future.) It is going to have it's own well dug in-situ and all four corners of the "H" will be sealed rooms dedicated to various functions with the environmental manager, generators, toilets and permaculture room all with their own ventilation arrangements.
Each hallway in the "H" is going to be fitted out for liveability and comfort and the entire complex underground is going to be so appealing it will be a nice place for my family to just take a vacation for the weekend in. I have already picked out the 50's style restaurant tables and padded seats I intend to install in the dining area. I am going to strive for a wide open feel with enormous room to swing your arms and a paint scheme that is pleasant and calming. I will have a Vault-OS terminal at your fingertips anywhere in the shelter for instant monitoring and control of anything at any time.
I have learned not only from my own mistakes but from the mistakes of others. I know a lot of the problems this guy in the video has had that are not mentioned but I am well acquainted with them. I won't be making them again.
The number one priority in shelter design should be liveability long term. I was heavily influenced by my hero worship of Oak Ridge laboratories when I built my last shelter to the detriment of functionality. This time I am going to be concentrating on the engineering for human beings who inhabit it above all other things. Just like the bright orange civil defense color I was using on this site the past ten years, I was more influenced by my preferences than I was by good judgement. I am changing that from now on and I am going to operate on what I have learned rather than what I necessarily prefer aesthetically.
Despite what may afford the most protection from radiation, the design of the entrances and exits are key to the usefulness of the shelter. The entrances should be designed to be convenient and accommodating as possible and then measures can be taken to increase their radiation protection. The truth is once you are 3 meters belowground all you need to do is properly shield against reflected neutrons and your shelter will be just as safe as my former design. This is best accomplished with water and metallic styrofoam to block incoming radiation from something as deadly as the neutron bomb which is guaranteed to be used in the next World War. China paid a lot of campaign money to Clinton and Gore through their Buddhist temple in California to get access to the neutron bomb. You can be certain they won't be putting conventional nuclear warheads on the tips of all those cruise missiles they are manufacturing like sausages over there. Why waste all that R&D expertise they got from research the Americans did for them over the past forty years?
